Microsoft has released the Windows 10 KB5099539 extended security update, which includes the July 2026 Patch Tuesday security updates for 570 vulnerabilities, along with additional security fixes.

Initially, Microsoft only offered consumers one year of extended security updates. However, last month, Microsoft quietly extended its free Windows 10 Extended Security Updates (ESU) program for consumers by an additional year, allowing enrolled devices to receives security updates until October 12, 2027.

If you are running Windows 10 Enterprise LTSC or are enrolled in the ESU program, you can install this update like normal by going into Settings, clicking on Windows Update, and manually performing a ‘Check for Updates.’
